C:Most Important Block (MIB)
Now What Is MIB?
It Isent Obtainable In Creative Nor Survival
Get It w Cheats By /Give [IGN] 137
COMMAND BLOCKAlso,To Get It To Teleport,/tp @p [x] [z] [y]
You Can Also Make It Do More Like /Time Set [ENTER TIME] Or /Msg @A Someone Has Triggered "----"'s Locked Chest!,command blocks execute their command when powered with redstone,so use this trick with locked chests

(Locked Chests Are In Latest SnapShot)
Also,@p Targets Nearest Player,@a Targets All Players & @r Targets A Random Player,so On a server with /kill,activate to kill a random player

Because I am more mature now.
